SPINNING AND BALLING MACHINE.

theater.

To all whom it concern:

Be it known that l, lionne E. WHrrooMB, a citizen of the United States, residing at Chicago, in the county of Cook and State of illinois, have invented certain new and useful Improvements in Spinning and Balling Machines, of which the following is a full, clear, and exact specification.

This invention relates to mechanism for winding threads, cord, twine, etc., into a cylindrical cop or ball in what is known as the universal winding and has special relation to a combination of such a machine with the spinning mechanism for forming the twine.

ln the manufacture of-binder twine, for

instance, it has heretofore been necessary,

in order to obtain a cop of uniform winding and maximum density, to first wind the twine on bobbins by special machinery and later deliver the twine from these bobbins to winding mechanism, and the object of this invention is to provide a form of winding mechanism that will receive the twine direct from the spinning mechanism and operate in conjunction therewith to make and wind the twine asl one operation while producing a dense andl evenly wound cop, thus eliminating the intermediate step of winding on bobbins with resulting economy in time and laborand reduction in the amount of machinery required.

This object has been accomplished 'by providing a machine in which the spinning and winding mechanisms are both driven from a single source of power, in this case an electric motor, and in which the twine which leaves the spinning mechanism at a constant rate is received by the winding mechanism and laid on the cop evenly and at uniform tension, the uniform action of the winding mechanism being obtained by employment of novel compensating means through which the reciprocative speed of the cop being wound is automatically synchronized with its rotative speed.

With the above named and other incidental objects in view, my invention consists of the organization, details of construction, parts, or their equivalents, hereinafter described and more'particularly deiined in the claims.

Having reference to annexed drawings,-

ln the present embodiment of my invention the mechanism employed consists of a suitable support 10 on which there is mounted. the driving element for the machine, in this case an electric motor 11. 'lhe armature of this motor is ixed to a hollow shaft 12, on one end of which is secured a yer 13, which is thus driven by the motor and which in turn drives the spinning mechanism shown at 14, from which the power is transmitted through the shaft 15 to a mechanism for preparing and combing the sliver, which is not shown. Mounted in such manner as to both rotate and reciprocate within the hollow shaft 12 is a hollow spindle shaft 16,

which is thus positioned on the axis of theY dle 17. At the opposite end of shaft 12 from,

that to which the flyer is fixed there is secured a driving gear 18 which is in geared Y relation with a shaft 19 adjacent thereto, which is mounted in suitable bearings on the supporting frame and is sleeved within a hollow shaft 2O to which it is connected by the friction drive or clutch 21. rlhe hollow shaft 20 has fixed thereto a gear 22 which meshes with a larger gear 23, secured to a sleeve 24, which is splined on shaft 16, which may thus reciprocate within the sleeve 21 but must rotate therewith. Sleeve 24 also has secured thereto a second gear 25 which transmits lan equal rate of speed to a gear 26 fixed on a hollow shaft 27 which is journaled onashaft 28 and mounted in suitable supports on the frame at the opposite side of shaft 1G from shaft 19. Shaft 28 has fixed thereto gear 29, which meshes with gear 18 and is driven direct from the motor. lt will be seen from the mechanism so far described that the flyer 13 will be driven direct from the motor at a relatively high rate of speed and that the spindle shaft 16 will also be driven from the motor and rotate inthe saine direction as the flyer, but at a somewhat reducedrate of speed through shafts 19 and 20 and the interposed friction Y collapsible spindle 17 controlled by a rod chronize this movement with its rotative movement, I provide on shaft 28, which is driven direct from the motor, and on hollow shaft 27, which is driven through sleeve 24, a differential planetary transmission which comprises a sun gear 30 onthe end of shaft 28 and a simi-lar sun gear 31 on shaft 27. These mesh with planetary gears mounted on a double carrier 32 which is journaled on shaft 28 and provided with the parallel arms 32a, on each of which a pair of planetary gears 32b is journaled. One pair of these planetary gearsv is in mesh with the sun gear 30 on shaft 28v and also with the teeth of an internalfgear wheel 33 which A. is fixed against rotation. The other pairof' planetary gears which is in mesh with the sun gear 31 on shaft 27 is also in mesh with the teeth of the internal gear wheel.l 34 which is journaled on shaft 27 and has fixed thereto and rotating therewith the'gear wheel 35. The gear wheel 35 meshes with a second gear wheel 36 which is secured to a cam shaft 37 journaled in suitable bearings on the supporting frame and carrying the cam 38'which has a peripheral 'cam groove 38a and on the end of the shaft 16 there is secured a clamp 39 which carries a depending pintle 40 which engages the cam groove 38a. A slotted guide plate 41l is preferably provided to guide the movement of pintle 40.

The mechanism above described constitutes the means by which the flyer and spindle are driven in unison and the cop spindle sumultaneously reciprocated within the flyer. The means for receiving and guiding the twine consists of the tension mechanism 42, which is of ordinary construction and receives the twine from the twistin mechanism at 14, stretching and 'drawing .1t ofi' and then delivering it to the guide 43 which is pivotally mounted intermediate its ends on one of the bars of the flyer andA which comprises the presser finger 43a provided with the necessary eye and grooves for reception of the twine or thread and with the weighted end 43b which is provided with an arcuate Slot 43c engaged with a pin on the flyer for limiting the rocking movement of the guide. With this construction the pressure of the guide finger on the cop is regulated by centrifugal force and is practically uniform at all times durin formation of the-cop, indicated at .44. he cop is held on the 46 which extends the length of shaftl 16 and has a projecting end 46a by which the rod is moved longitudinally to collapse and eX- pand the spindle, This particular structure forms no part of my present invent-ion.

The operation of the mechanism above described is substantially as follows: the

twine being wound is roduced at aconstant rate of speed byft e spinning mechalwill decrease just sufficiently to allow the nism and passes from the tension mechanism 42 to the guide element 43, from which it is delivered in spiral windings to the cop on spindle 16. With the mechanism in action and the cop being started, the flyer 13 and the spindle 16 are both-rotated in the same direction at high speed, but owing to the gear relation between the motor and spindle drive, the spindle normally rotates at somewhat slower speed than the flyer and their difference in speed represents the rate at which the twine is wound on the cop. As the cop grows in size the drag of the flyer against the cop and the spindle shaft increases and tends to rotate this shaft at nearer its own speed. When this drag becomes sufficient, slippage occurs in the clutch 21 and the speed of shaft 16 becomesgradually greater than its normal drive speed. As this occurs sleeve 24 and therefore shaft 27 are given increased speed, which is communicated to the differential mechanism, the action of which is such as to decrease the rotative speed of gear 34 and consequently of the cam shaft 37 and of the reciprocative speed of the spindle shaft 16 in proportion as the speed of shaft 27 land sun-gear 31 increases. It therefore follows that as the cop increases-in size its rate of reciprocation twine to 'be placed in close and even spirals on the cop and that this action will be wholly automatic.

The mechanism above described exemplifies but one form which my' invention may 100 take and it will be evident that other arrangements of -the essential elements and substitution of equivalent means are possible within the scope of the appended claims.
